Title: Control system for hydraulically operated elements or systems
IPC: B66D1/50
Filed: 1979-06-08
Abstract: Apparatus and method for controlling the operation of two separately operable hydraulic arrangements such as elements, units circuits or systems, and in particular the winches (1P, 1S) for the warps (2P, 2S) of a fishing trawl by monitoring the pressure conditions in the arrangements, i.e. warp tension, by transducers (45P, 45S). A reference pressure for the operating condition of the whole arrangement is established and the individual pressures are compared with the reference pressure in a comparator (54) to produce control signals which are used to vary the pressure conditions of the individual arrangements to make them equal to the reference value. Overall control is by a microprocessor (55) which allows the system to deal with obstructions and provides alarms and safety conditions when necessary. The initial and final stages of shooting and hauling are achieved using manual control. <IMAGE>

Title: Biological Purification of Liquids
IPC: C02F3/30
Filed: 1979-08-02
Abstract: In the biological purification of a liquid, a batch of the liquid is contacted in a treatment space with micro-organisms present in that space from a preceding treatment. During or after supply of the liquid, oxygen is supplied to the treatment space until the desired degree of purification has been reached, after which the liquid becomes quiescent and the substances suspended in the liquid can sedimentate. The clarified liquid present above the sediment is drawn off, and the slit remaining in the treatment space and containing micro-organisms is stored therein under such conditions that their activity remains conserved to a sufficient degree until the supply of the next liquid batch. The amount of the stored silt is varied according to what is needed for treating the next batch, the surplus silt being removed.
Patent GB-2037510-A (GB)
Title: Arc Monitor for Electrical Discharge Machining
IPC: B23H7/16
Filed: 1979-09-26
Abstract: Undesired arcing in an EDM process is distinguished from the normal sparking by passing a signal (22), representing the voltage across the gap between an electrode and a workpiece, through a filter 24 which selects those frequencies which have a significantly greater amplitude during sparking than during arcing. The relevant frequencies are in the band 1-8 MHz, but it is sufficient for the filter 24 to be high pass with a cut-off in the range 1-4 MHz. The voltage across the gap is also applied to a comparator 25 which detects any discharge (arc or spark) across the gap by determining whether the gap voltage is between two levels. The proportion of discharge time in which arcs occur is derived by a time-divider circuit 32 which receives signals after processing from the filter 24 and the comparator 25. <IMAGE>

Patent GB-2047491-A (GB)
Title: Oscillator mode suppression apparatus having bandpass effect
IPC: H03B5/32
Filed: 1979-11-12
Abstract: An apparatus utilizing the basic oscillation characteristics of the Colpitts or Pierce and Hartley oscillator configurations. In this embodiment the basic shunt reactive shunt arms (14, 16) are replaced with a selected pair of tank circuits or one of the shunt arms with a series or parallel tank circuit. These tank circuits are tuned such that the sign of their effective reactances are the same between the range of resonant frequencies of the individual tank circuits or of the series and parallel resonant frequencies of the series-parallel tank. When this occurs and their sign differs from the sign of the effective reactance of the series reactive element, there is an 180 DEG signal phase shift in the feedback loop, and therefore oscillation. Resonator 12 is a crystal. Other examples of the shunt arms are described Figs. 3a-3e. <IMAGE>
Patent GB-2063434-A (GB)
Title: A Furnace, for Example, for Heating Ceramic Objects
IPC: F27B3/02
Filed: 1979-11-16
Abstract: The furnace has a furnace space (4) and at least one burner (13, 14) providing flame or hot combustion gases to the furnace space. A gap (24) is provided as an outflow opening for combustion gases from the furnace space (4). This gap (24) acts as a throttle so that the pressure within the furnace space builds up. This prevents the formation of cracks in ceramic objects during heating in the furnace space. In addition, the combustion gases are confined to flow through conduits (25, 26) defined between panels (20, 21) of heat transmitting material and the inner surface of the furnace space. Heat from the gases within the conduits (25, 26) is thus supplied to the furnace space (4) such that the heating up period is short. <IMAGE>

Patent GB-2039703-A (GB)
Title: Unit for harvesting cabbage plants
IPC: A01D45/26
Filed: 1979-06-27
Abstract: The unit according to the invention concerns a cabbage harvester consisting of a lifter part with conveyor belts which will for one thing pull the cabbages up by their roots and secondly transport the cabbage plants lifted on to a topping device (18, 20, 21). The unit will harvest cabbage plants without damaging these, contrary to other cabbage harvesters, so that the cabbage plants may be used for direct sales. This is rendered possible by applying an actually known topping device (18, 20, 21), which has been mounted in such a way at the rear end of the lifter part that the cabbage plants are caught in their upright position, i. e. the centre of gravity being above the rods. After the rootstocks (33) have been cut from the heads (32) these are, by a steering device, carried over into a transport box, possibly via a conveyor belt.

Title: Metal-air electric cell
IPC: H01M12/06
Filed: 1980-07-10
Abstract: A metal air electric cell uses cobalt phthalocyanine as a catalyst in its cathode assembly to promote electrochemical reduction of the positive active material, oxygen, and obtains increased output with extended service life. A button cell (10) comprises a cathode cup (11) secured to an anode cup (12) with an insulating seal (14) in between. The anode cup (12) contains a metallic material (13) mixed with electrolyte and this is separated from a cathode assembly (15) by a separator (33) which prevents electronic conductance but does not inhibit ionic transport. The cathode assembly (15) includes cathode material (32) incorporating cobalt phthalocyanine catalyst and encompassing a current collector grid (31) electrically connected to the cathode cup (11). A permeable hydrophobic member (30) is provided between the cathode assembly (15) so that gas entering and leaving the cell via openings (20,21) in the cathode cup (11) must pass through the hydrophobic member (30), and a diffuser (16) provides for even distribution of gas entering the openings (20,21) to the cathode assembly (15). <IMAGE>

Title: Stiffening a heel end portion of a shoe upper
IPC: A43B23/16
Filed: 1980-08-06
Abstract: In stiffening the heel end of shoe uppers using long stiffeners extending through to the joint region of a shoe, solvent-activated stiffeners (limp and difficult to insert) are presently used, which stiffen as solvent evaporates before the last is slipped. Heat-activated stiffeners are too stiff in the waist region to last satisfactorily without reheating. In the invention the heel end is stiffened using a stiffener of which the wing portions are rendered flaccid by solvent, the stiffener then being processed in the same manner as a heat-activated stiffener, that is assembled and laminated with upper components by heating in a suitable apparatus followed by backpart moulding to set the solvent-free central region of the stiffener in a desired shape, the upper subsequently being lasted to set the upper in the desired shape, the upper remaining on the last sufficiently long for the solvent to evaporate.

Title: Double action press having floating punch
IPC: B21D22/20
Filed: 1981-05-05
Abstract: A double action mechanical press, especially for performing a blanking operation and a forming operation on each cycle thereof, having a first slide 24 and a second slide 21, wherein the slides have separate strokes and are reciprocated by means of a crankshaft. A preloaded antifriction bearing 154 guides a blanking punch 66. A forming die 188 is connected to the press slide 24. The punch 66 is formed as a piston and is urged downwardly by pressurized air. The travel of the punch against the pressurized air enables the punch to abut the top of the strip material until the blanking slide strikes it and causes it to blank out the part. The forming die draws the blanked out part, which is continued to be held by the pressure of the punch against the liftout ring 86. <IMAGE>
